Description

Technical Field

[0001] The utility model relates to the technical field of flow meter detection, in particular to an air tightness detection mechanism of a flow meter. Background Art

[0002] Flowmeter is an instrument that indicates the measured flow rate and / or the total amount of fluid in a selected time interval. In simple terms, it is an instrument used to measure the flow rate of fluid in a pipeline or open channel. Measurement is the eye of industrial production. Flow measurement is one of the components of metrology science and technology, and it is closely related to the national economy, national defense construction, and scientific research. Doing this work well plays an important role in ensuring product quality, improving production efficiency, and promoting the development of science and technology. Especially in today's era of energy crisis and increasing automation of industrial production, the status and role of flowmeters in the national economy are more obvious.

[0003] During the production process of the flowmeter, it is necessary to perform an air tightness test on it. After searching, the Chinese patent CN220084250U in the prior art discloses a small-caliber flowmeter air tightness test device, including: a shell; a test mechanism, and the test mechanism for testing the air tightness of the flowmeter is installed in the inner cavity of the shell. The utility model sets a plugging test component. When testing small-caliber flowmeters of different models, the flowmeter is placed on the top of the installation component, and the servo motor is turned on synchronously. The servo motor drives the bidirectional screw to rotate, and the fixed plate is connected to the bidirectional screw through a thread. When the bidirectional screw rotates, it drives the two rubber plugging heads to move inward synchronously, and the two rubber plugging heads block the two ends of the flowmeter through their own elasticity. At the same time, the air pump injects gas into the inner cavity of the flowmeter for testing through the connection with the hose, which facilitates the testing of flowmeters of different models and increases the versatility of the device.

[0004] However, during the use of the utility model, since the air pump injects gas into the flow meter, when the flow meter leaks, the injection staff cannot accurately observe whether there is a leak and the location of the leak, which affects the accuracy of the detection and cannot meet production needs. Therefore, a flow meter air tightness detection mechanism is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a flow meter air tightness detection mechanism having the advantage of high detection accuracy. It solves the problem that when an air pump injects gas into the flow meter, when the flow meter leaks, the injection staff cannot accurately observe whether there is a leak and the location of the leak, which affects the accuracy of the detection and cannot meet the production needs.

[0006] To achieve the above object, the utility model provides the following technical solutions: a flow meter air tightness detection mechanism, comprising a base and a top plate arranged on the top of the base, two support plates are fixedly connected between the top plate and the base, a lifting platform is arranged between the two support plates, and a detection mechanism is arranged on the top of the lifting platform;

[0007] The detection mechanism includes two mounting plates fixedly connected to the top of the lifting platform, one side of the mounting plate is fixedly connected to an electric push rod extending to the other side, the output end of the electric push rod is fixedly connected to a connecting plate, one side of the connecting plate is fixedly connected to a conical sealing head, the top of the base is slidably connected to a water tank, the top of the base is fixedly installed with an air pump, and a hose is fixedly connected between the air pump and the conical sealing head.

[0008] Furthermore, there are two air pumps, which are symmetrically distributed on the left and right sides of the water tank, and clean water is injected into the water tank.

[0009] Furthermore, the top of the lifting platform is fixedly connected to a mounting box, the interior of the mounting box is fixedly connected to a guide rod, the exterior of the guide rod is slidably connected to a sliding sleeve, and the top of the sliding sleeve is fixedly connected to a connecting block extending to the top thereof.

[0010] Furthermore, one end of the connection block away from the sliding sleeve is fixedly connected with a clamping piece, and a rubber pad is fixedly connected to the inner wall of the clamping piece.

[0011] Furthermore, a partition is fixedly connected inside the installation box, the guide rod passes through the partition and is fixedly connected thereto, and a slide groove adapted to the connection block is provided inside the installation box.

[0012] Furthermore, a dual-axis motor is fixedly installed on the top of the top plate, and two groups of fixed plates are fixedly connected to the top of the top plate. A winding drum is rotatably connected between each group of fixed plates, and the external transmission of the winding drum is connected to a cable extending to the bottom of the top plate.

[0013] Furthermore, the output shaft of the dual-axis motor is fixedly connected to one end of the winding drum, and the bottom end of the cable is fixedly connected to the top of the lifting platform.

[0014] Compared with the prior art, the utility model provides a flow meter air tightness detection mechanism, which has the following beneficial effects:

[0015] 1. The air tightness detection mechanism of the flow meter is provided with an electric push rod to drive the conical sealing head to move, so that the conical sealing head can be connected with the flow meter, and then the flow meter is lowered into the water tank by providing a water storage tank. By providing an air pump and a hose, the outside air can be injected into the flow meter. At this time, if bubbles appear in the water tank, it can be judged that the flow meter is leaking, thereby achieving the effect of air tightness detection of the flow meter, and enabling the staff to draw conclusions more intuitively.

[0016] 2. The air tightness detection mechanism of the flow meter enables the sleeve to move on its surface by arranging a guide rod, and then arranging a clamping piece. On the one hand, it is convenient to fix the flow meter, and on the other hand, it is convenient to adjust the distance between the two clamping pieces according to the size of the flow meter to be suitable for flow meters of different sizes. This solves the problem that when the flow meter leaks due to the air pump injecting gas into the flow meter, the injection staff cannot accurately observe whether there is a leak and the location of the leak, which affects the accuracy of the detection and cannot meet the production needs.
